- the present invention further relates to an aircraft and a method of data communication using such a network.
- the present invention is in the field of wireless communication networks, in particular in the aircraft sector.
- Wireless networks are well known in various applications.
- Such wireless network architectures are usually based on a so-called star topology, in which a single central master is present, for. B. a WLAN access point, and various connected to this master slaves or clients. If the central master of the wireless network fails, the entire wireless ⁇ loose network is disabled or at least has a significantly reduced functionality.
- such wireless networks built on a start topology are not very robust.
- the distribution of data in such wireless networks is very ineffective because the master must always distribute the data one after the other to the different clients.
- so-called mesh networks which are also referred to as ad hoc networks, are increasingly being used as wireless communication networks.
- a mesh network is to be understood as meaning a radio network which connects a plurality of network nodes, that is to say terminals in a telecommunications network, to form a meshed network.
- data in a mesh network is transferred from a network node to a network network.
- IFE In-Flight Entertainment
- PES Passenger Service System
- IFE systems used today in the aircraft are constructed in a wired data communication and have a complex, wired communication network on the basis of which ⁇ .
- US 2005/0074019 A1 describes a multi-level wireless mesh network and a data communication method to allow data communication between network nodes of different levels of this ad hoc wireless network.
- the individual network nodes which are equal to one another in the various levels, are mobile.
- the network nodes are dynamic, meaning that they have no fixed configuration. Rather, the arrangement of the network nodes is variable and must be redefined for the data communication in each case, that is to be configured, which entails a considerable configuration outlay for data communication.
- the present invention has for its object to provide an improved and in particular flexible data communications, particularly in an aircraft make meetzu ⁇ . - -
- this object is achieved by a network having the features of patent claim 1 and / or by an aircraft having the features of patent claim 12 and / or by a method having the features of patent claim 15.

- the of the present invention is based on finding is that in growing vehicles, especially in large-capacity passenger aircraft, the hardware components within a so-called IFE system always be on ⁇ wecker, which in particular is associated with an increasing weight-gain.
- the present invention is based on the idea of replacing the hardwiring known from previous conventional data communication networks in vehicles and the associated hardware outlay with a static mesh network with fixed network nodes.
- Such mesh networks are funkba ⁇ catalyzed communication networks which may communicate via wireless communication links depending on the application mitein ⁇ other. This already can be a significant weight reduction Ge ⁇ in the implementation of such communication networks in vehicles realize what particular with
- Aircraft of particular interest and advantage is because there weight reduction plays an essential role.
- the invention provides a hierarchical architecture of the mesh network with different network layers. - -
- the network nodes of different network levels are according to the invention not equal, i. the network nodes of higher-level network levels are z. B. more dominant than rank lower network nodes.
- the various network nodes within the different network levels are interconnected via configurable communication links, so that there is very robust data communication between the individual network nodes, which remains functional even in the event of a failure of one or more of the network nodes within the mesh network.
- Another advantage in providing an inventive mesh network is that a near infra ⁇ structureless and especially serverless network architecture is provided with the exception of hardware for
- Nettechnikknoten requires a minimum amount of hardware and interconnections and because of this is very uitef ⁇ fective and weight-saving.
- a high flexi- is formality in the structure of the static mesh network given wel ⁇ ches can be adapted to a variation of the layout of the network nodes, in particular a change in the layout of the aircraft cabin, adapted very flexibly according to need and application ,
- a network node is understood to mean an electronic terminal with mobile communication capability in a communication network, such as in the case of an aircraft a passenger-specific multimedia device, a monitor, a personal television device (PTV device), a passenger-individual computer, a mobile phone, personal digital assistant (PDA), a No ⁇ tebook or any other electronic component with mobile communication capability.
- a network node is thus a generic term for a device which connects two or more transmission paths, which may be wired or wireless, of a communication network.
- the characteristic of such network nodes is in each case the addressability.
- the positions of the individual network nodes of the static network can be configured via the known cabin layout and can therefore be changed.
- a static network such a network is to be understood, which does not have to be rebuilt again and again and configured as plants ⁇ in mobile network is the case. This is because if the network is static, the initial configuration of the network and the
- the new positions of the network nodes are nevertheless determined by the known layout and thus do not always have to be reconfigured.
- a previously defined configuration of these network nodes and thus of the entire static mesh network is already available via a known layout, for example the known cabin layout.
- a complex hardware for reconfiguring in the event of a change in the individual network nodes is therefore unnecessary, which leads to a significantly simplified network architecture and above all to a much faster and above all simplified communication.

- the entire mesh network has a multiplicity of different network levels and, in particular, a multiplicity of different network nodes, in particular in the underlying second network level.
- the provision of two or more gateway network nodes is advantageous, thereby providing a faster and more effective and, above all, more robust data forwarding. This ensures that, in the event of a failure of a gateway network node, effective and secure data communication with network-external systems is nevertheless possible.
- the mesh network has three or more different network levels, with a first, topmost network level having at least one gateway network node functioning as a gateway, via which the mesh network can be coupled to network-external systems, without wires or wires ,

- a third, lowest network level has a multiplicity of end network nodes, which each form wireless data-communicative connections with at least one base network node of the second network level. The network nodes, which can each be brought into data communication with the network nodes, form the end of the mesh network chain.
- the basic network nodes are designed to establish a data communication connection on the one hand to the gateway network nodes and on the other hand to the network nodes.
- the network nodes of the upper, first network level act as a gateway to the network nodes of the underlying second network level and to other interface systems that are not necessarily part of the mesh network.

- the base network nodes of the overlying network planes within the cabin layout are arranged such that a data-communicative connection is established with a minimum number of base network nodes _ _ _ _ _
- the number of base network nodes used in this case depends essentially on the number and layout of the final network nodes within the section and in particular in ⁇ nerrenz the aircraft cabin.
- the various network nodes each have an independently operating transceiver for receiving and / or transmitting data.
